I'm having the same problem as above and I have done everything listed above but the only difference is I have Linux Mint installed with a ZFS file system attached to /Server and everything runs from that drive.

All the directories can be seen by filebot but all the files are greyed out and the /Server directory cannot be seen.
Filebot 4.7.9 still works fine and I'm not after a refund as I have used your program for years so I'm happy to pay.
